When it comes to demand, we believe that customers want to maximize utility, which is what drives their behavior. When it comes to supply, we believe that producers are trying to maximize profit, and this aim drives their behavior. Firms attempt to make a profit by repurposing resources into marketable goods.

Firms that survive and develop over time are those that are more innovative and lucrative. Firms that are not profitable eventually collapse. Every year, millions of new businesses open their doors.

Many people quit the market. The firm's decision-makers must decide which items to sell and services to create, as well as the resources to use. They must make preparations while dealing with uncertainty regarding customer demand, resource availability, and other people's intentions.

The explicit expenses of a company are its real cash payments for resources like labor, rent, interest, insurance, and taxes. In addition to these direct financial outlays, or explicit costs, the business incurs implicit costs, which are the opportunity costs of employing resources held by the firm or given by its owners. Examples include the usage of a company-owned facility, the use of company cash, or the owners' time.

• The term, “explicit cost” refers to the opportunity cost of resources employed by a firm that takes the form of cash payments.

Implicit costs, like explicit costs, are opportunity costs. However, unlike explicit costs, hidden costs, of which these Costs necessitate neither a cash payment nor an item in the firm's financial statement, keeping track of its revenues, explicit costs, and accounting profit.

• The term, “implicit cost” refers to a firm’s opportunity cost of using its own resources or those provided by its owners without a corresponding cash payment

Economic profit is defined as total revenue minus all expenses, both implicit and explicit; economic profit considers the opportunity cost of all resources utilized in production. Exhibit 1 shows that an accounting profit of $64,000 minus implicit expenses of $52,200 results in an economic profit of $11,800.

• The term “AVC” is abbreviated for average variable cost, for which the Variable cost is divided by output or AVC = VC/q

• The term “ATC” is abbreviated for the average total cost, for which the total cost divided by output or ATC = TC/q; the sum of average fixed cost and average variable cost, or ATC = AFC + AVC

Although the marginal cost is the most important, the average cost per unit of production is equally important. We can tell the difference between average variable cost and average total cost.

These measurements are shown in the image attached above as Exhibit 6 columns (5) and (6). Column (5) shows the average variable cost, or AVC, which is equal to the variable cost divided by the output, or AVC VC/q. The last column shows the average total cost, or ATC, which is equal to total cost divided by output, or ATC TC/q. Each metric of the average cost falls first as output expands, then rises.

Wanda Wheeler's earnings as an entrepreneur are based on economic profit, as the entrepreneur—a sum in excess of what her resources might yield at their peak of N alternate application. What would happen to the accounting statement if Wanda decided to make a change? Do you pay yourself a salary of $50,000 each year? Explicit expenses would rise by $50,000, and the implicit expenses would be reduced by $50,000. As a result, accounting profits would fall by $50,000.

There is one more profit metric to think about. A normal profit is defined as the accounting profit that is just enough to guarantee that all resources utilized by the business earn their opportunity cost.

When accounting profit equals, Wheeler Dealer gets a regular profit. One of which are the hidden costs—the total of Wanda's normal work compensation ($50,000) and the interest by utilizing her personal funds ($1,000), as well as rent, ($1,200) garage Thus, if the annual accounting profit is $52,200—the opportunity, the price of resources Wanda provides services to the enterprise, and the corporation makes a regular profit.

Accounting profit can be separated into a regular profit and economic profit if it is significant enough. Wanda's business made $64,000 in accounting profit, which includes (1) a typical profit of $52,200, which compensates her implicit costs—the opportunity cost of the resources she provides to the company and (2) a monetary profit of $11,800, which is in excess of what these resources, Wanda's time, for example, might be put to better use.

Wanda is better off owning her own business as long as the economic profit is favorable, as opposed to working for Skyhigh Aircraft. If total revenue had been $50,000, an accounting profit of $9,000 would have covered less than one-fifth of her pay, to say nothing of other benefits.

The firm's production function refers to the link between the number of resources used and the overall product. The marginal product of a fourth worker is smaller than that of a third worker. Hiring additional employees raises the overall product by decreasing amounts, thus the marginal product falls after three workers. The rule of decreasing returns applies to the fourth worker.

The law of marginal returns takes effect. According to this law, marginal product decreases when more of a variable resource is coupled with a given amount of another resource.

The most essential aspect of production is the law of declining marginal returns.

• The term “economies of scale” refers to Forces that reduce a firm’s average cost as the scale o operation increases in the long run

A firm's long-run average cost curve, like its short-run average cost curve, is U-shaped.

Remember that the form of the short-run average total cost curve is largely influenced by growing and decreasing marginal returns on the variable resource. The long-run cost curve is shaped by a different principle. When a company achieves economies of scale, its long-run average cost lowers as output grows. Consider the following sources of scale economies.

A bigger size frequently allows for larger, more specialized machinery and higher worker specialization. Compare, for example, a tiny restaurant's household-sized kitchen to a McDonald's kitchen.

When productivity is low, the smaller kitchen produces meals at a lower average cost than McDonald's. However, if output in the smaller kitchen exceeds, say, 100 meals per day, a larger kitchen on the scale of McDonald's would produce meals at a lower average cost. As a result of economies of scale, the long-run average cost of a restaurant may decrease as its size grows. For example, the McDonald's snack wrap was inspired by a franchisee's suggestion that the firm discover new applications for the pieces of chicken supplied with dipping sauce. Selling more chicken allowed each restaurant to cook new batches more often, resulting in a fresher product for consumers.
